When we think about cybersecurity, so much attention is given to safeguarding against threats and preventing breaches. However, when a breach does occur, it's equally important to know how to analyze and understand what happened. This is where 'types of forensics', or cybersecurity forensics, comes into play. By using an assortment of techniques, we can unravel the mystery of a security incident, learn how to prevent similar incidents in the future, and possibly even catch the responsible parties. Understanding the realm of forensics in cybersecurity is not just beneficial; it's a necessity in our digital era.

Cybersecurity forensics or digital forensics marks a specialized area of cybersecurity, which deals with the detection, mitigation, and prevention of cyber threats. However, it's crucial to note that there are several distinct types of forensics each with their uniqueness and specialized tools.

Network Forensics

Network forensics centers on monitoring and analyzing computer network traffic for information gathering, legal evidence, or intrusion detection. Professionals in the field capture, record, and analyze network events to discover the source of security attacks or other problem incidents. Techniques such as traffic capture and packet-level analysis, combined with sophisticated software tools, form the foundation of network forensics.

Digital Forensics

Digital forensics focuses on evidence found in computers and digital storage devices. The goal of digital forensics is to explain the exact nature of a digital crime in the IT environment. This could involve uncovering the sequence of events that led to the cyber attack or working out the exact time and date when a system was compromised.

Email Forensics

Email forensics involves the recovery and analysis of email traffic, which could include deleted mails and chat conversations. An email forensic investigation is focused on understanding a cyber-criminal's motives, tracking their activities, and collecting potential evidence for legal proceedings.

File System Forensics

This type dives into the structure and contents of hard drives and various storage systems. Data recovery is the typical goal here, with an emphasis on deleted files, partitions, or formatted hard drives. More granular, this could include analysing file format structures, understanding file metadata, or even retrieving images from raw binary data.

Malware Forensics

Malware forensics involves the analysis of malicious software, such as viruses, worms, and Trojans. This process aims to understand how the specific malware works, which vulnerabilities it exploits, and how to protect systems from it. Techniques include static analysis (evaluating the malware without executing it) and dynamic analysis (running the malware under controlled environments).

Incident Response Forensics

Incident response forensics follow a systematic approach to manage and investigate the aftermath of a suspected cyber incident or attack. It aims to limit damage and reduce recovery time and costs by handling the situation efficiently and comprehending the specifics of the incident.

Memory Forensics

Memory forensics covers the analysis of the data stored in volatile memory (RAM). By studying a snapshot of memory, analysts can identify running processes, open network connections, and other details that yield vital information about what was happening on a system at a particular point in time.

Mobile Forensics

Note the emergence of smartphones and mobile devices in the digital space. Our handheld devices carry as much, if not more, data than our desktop computers. Naturally, the study of this data for evidence, known as mobile forensics, became an essential sub-discipline in digital forensics. It involves the recovery of digital evidence or data from a mobile device under forensically sound conditions.

In conclusion, these 'types of forensics' epitomizes how broad and diverse the world of cybersecurity forensics is. From investigating networks to analyzing malware, echo the importance of specialized roles in the cybersecurity industry. As our reliance on digital technologies deepens, the need for skilled experts in all types of forensics will only grow. So, whether you're considering a career in this field or simply want to understand more about the security of your own systems, having a solid understanding of these different types of forensics is crucial.
